2.1.1.2. Voltage output If the flow meter is configured for a voltage output, the signal will be available as a positive potential on pin 4 relative to pin 3 of the terminal strip. Since these pins are galvanically isolated, the signal cannot be read by an indicator between pin 4 and pin 1 of the terminal strip. Pin 3 must be used as the return to properly read the output on pin 4. If an output that is referenced to power supply common is desired then pins 3 and 1 must be connected. It

half or full duplex; and jumper 5 is enabled when a hardware override of the baud rate (forcing it to 9600) is desired. These functions are summarized in Figure 2-6. 2.7.2. RS-485 If RS485 is specified on the order, the flow meter is set to the default values: address 61, unterminated Tx and Rx lines. While the default address is 61, all instruments will respond to an address of FF. Hardware settings for RS-232 and RS-485 are enacted on 12 pin jumper field located on the left end of t

Since the alarms act as switches they do not produce a voltage or current signal. However, they can be used to generate a voltage signal on an Alarm Out Alarm 1 line. This is done by connecting a suitable pull-up resistor between an external voltage supply and the desired alarm line while connecting Alarm Common to the common of the power supply. When activated, the alarm line voltage will be pulled toward the alarm Alarm 2 common line generating a sudden drop in the signal line vo

2.2. Rotary Gas Selector Record# Gas The Hastings 400 Series flow meters can have up to eight different calibrations 0 Nitrogen stored internally. These are referred to as gas records. These records are used to select different gases, but they can also be useful in other ways; for instance 1 Air reporting the flow in an alternate range, flow unit or reference temperature. 2 Helium The records are referred to by their number label from #0 – #7. 3 Hydrogen 4 Argon The first six records

1. General Information 1. General Information 1.1. Overview 1.1.1. 400 Series Family The Hastings 400 Series is a family of flow instruments which is specifically designed to meet the needs of the industrial gas flow market. The “I” family in the 400 Series features an IP-65 enclosure which allows the use of the instrument in a wide variety of environments. The 400 I products consist of four configurations: a flow meter, HFM-I-401, which has a nominal nitrogen full scale between 10 SL

2.4. Mounting the Electronics Remotely In order to maintain the integrity of the Electrostatic Discharge CAUTION immunity both parts of the remote mounted version of the HFM- I-400 instrument must be screwed to a well grounded structure. The ferrite that is shipped with the instrument must be installed on the cable next to the electronics enclosure. The electronics enclosure can be separated and relocated up to 30 feet away from the flow meter base. This requires a cable which is

There are two possible connection methods to the analog terminal strip. The standard method is by inserting a cable through the supplied cable gland with an external jacket that meets the specifications of the following caution note and tightening down the cable gland nut securely to seal against the cable jacket. There is also an optional sealed circular connector that may be ordered with the instrument. If this connector is ordered the internal terminal board will be connected to pins

the range of 5-28 Vdc from a source external to the flow meter. The loop supply can be the same supply as that for the instrument power or it can be an isolated loop supply. Figure 2-3 shows a typical setup using the same supply. This method requires a jumper from pin 2 to pin 4 on the terminal strip while connecting pin 3 to a wire that carries this signal to the indicator (for example, a process ammeter, data acquisition system, or PLC board). To complete the current loop, another wire
